sorry to say this but i can tell that you are a noob when it comes to things like these. The reason is that if you wasnt a noob you would know that a crappy pc can run even the latest games such has oblivion. the catch is that the game will look crap compared to running the game at high settings.
now my point is simple, if u dont have a super pc, users should then be able to play the game at ps2 graphics while others with super computers should be allowed to play this game at 360 graphics easily.
judging from the screen shots and vidoes of the 360 version, even a MID range pc can play it at that much detail.
konami are just lazy in some departments, i know now that their is no such thing has a perfect football game. konami can easily make pes6 the perfect footy game, if not near perfect such has more licence , better graphics and better online play
